Describe how does the motor develops torques in a systematic way
Most dc voltmeters produce a reading equal to the average value of the voltage measured. The mathematical definition of the average value of a periodic waveform is Vavg = 1/T ∫0T v(t)dt, in which T is the period of the voltage v(t) applied to the m..
A soccer player kicks a soccer ball of mass 0.45 kg that is initially at rest. The player's foot is in contact with the ball for 1.1 x 10-3 s, and the force of the kick is given by F(t) = [(6.1 x 105)t - (2.3 x 108)t2] N for 0 t 1.1 x 10-3s, where ..
Assume the resistance of a certain type of resistor is normal distrubuted random variable with mean =12.8 ohms and standard diviation of =1.3ohms. if a single reistor is to be randomly selected from the process producing resistors.
Design a circuit with minimum number of gates for a binary multiplier that multiplies two unsigned four-bit numbers, Using Inverters, AND, OR gates and Full Adders.
Gaussian white noise, perfectly band-limited to 0-10MHz, is passed through a perfectly rectangular filter of bandwidth 18 kHz, gain 3 dB, and center frequency 455 kHz. If the RMS voltage of the input noise is 1 volt
When calculating the bending stress of a rectangular plate, one must use the section modulus about the neutral axis of the plate. This axis is at the center of the plate where there is neither tension nor compression.
A body attached to earth ground by an electrical conductor is at zero electrical potential. A charge of 25 C is added to the body. What is the potential of the body now. Explain.
A step index fiber with refractive indices n1 = 1.45 and n2 = 1.44 operates at lambda = 1.55 micrometer.Determine the core radius at which the fiber V parameter is 10.Use the numerical method to determine the effective indices of all the supported mo..
A power amplifier employs an output stage whose gam vanes from 2 to 12 for various reasons. What is the gain of an ideal (non varying) amplIfier connected to drive it so that an overall gain with feedback of 100 ± 5% V/V can be achieved
1.A shunt-connected DC motor operates at its rated terminal voltage. Its no-load speed is200 radians/second. At its rated torque of 500 Nm, its speed is 180 radian/second. Themotor is used to directly drive a load whose load torque TL depends on its ..
A volume charge density of K Coulombs per cubic meter resides uniformly within the material of a long cylindrical shell whose inner radius is 1 m and whose outer radius is 3 m. Find D and E in all regions.
The light from a cameras electronic flash is produced when a high voltage obtained by charging a capacitor is applied to electrodesin a xenon-filled flash bulb. (a) to what voltage would a 60-microfarad capacitor be charged by a6mA current lasting ..
